Patent CA-2232864-A1 (CA)
Inventor: BRAZDRUM HELMUT
IPC: H04L49/111
Filed: 1996-09-26
Abstract: There is a hardware configuration with processing units (CTR0, CTR1) operated in microsynchronous parallel operation for the processing of ATM information which are connected at the ATM end to a switching matrix (SN0, SN1) and via a bus interface (B-I) to a central processor which is used for evaluating error statistics arising in the processing units and for monitoring the synchronous operation by comparing the processing results. The error statistics data are packed into ATM transmitter cells and looped back via the switching matrix in each case to both processing units and then supplied to the central processor via the bus interface. This prevents the erroneous indication of the loss of microsynchronism when error statistics for the two processing units differ (Figure).
Patent CA-2235209-A1 (CA)

Filed: 1998-05-19
Abstract: A method and an apparatus for handling interrupt requests generated by a plurality of interrupt sources (2A, 2N) for a processor. The method includes steps of scanning interrupt registering means (8) for determining a current interrupt request to be sent to the processor among interrupt requests having respective interrupt flags inputted in said interrupt registering means, and steps involving the processor for execution of an interrupt processing program according to the result of a comparison of a scanned interrupt flag with a predetermined flag value, characterised in that it includes a step of latching a flag corresponding to a first occurring interrupt request from a source in a group of sources into interrupt latch registering means (7) for further processing and for blocking further interrupt requests from at least the same source in the same group from having aflag latched before processor controlled resetting.

Title: Systems and methods for electrosurgical myocardial revascularization
Inventor: THAPLIYAL HIRA V
IPC: A61B19/00
Filed: 1996-11-22
Abstract: A method for trans-myocardial revascularization of the heart of a patient includes positioning an active electrode surface (82) in close proximity to a target site on the wall of a patient's heart, and applying high frequency voltage between the active voltage surface (82) and a return electrode (56) to ablate tissue at the heart wall. The high frequency voltage ablates, i.e., volumetrically removes the heart tissue, and the electrode surface (82) is axially translated into the space vacated by the removed tissue to bore a channel through the heart tissue. The active electrode surface (82) may be introduced into the thoracic cavity and placed adjacent the epicardium to form an inward channel toward the ventricular cavity of the heart and positioned adjacent the endocardium to form a channel extending outward towards the epicardium. In either case, the channels formed through the myocardium promote direct communication between blood within the ventricular cavity and that of existing myocardial vasculature to increase blood flow to the heart tissue.

Title: A method to provide information concerning a frequency band, a head-end, a network terminator and a terminal realizing such a method and a communication access network including such a head-end, such a network terminator and such a terminal
Inventor: VANHOOF HARRY FRANCISCUS LUDOV
IPC: H04N7/173
Filed: 1998-07-09
Abstract: A method to provide information in a communication access network which includes a plurality of terminals (T12, T12, T13, ..., T31, ...) and a head-end (HE): The head-end (HE) includes transceivers (TRX1, TRX2, TRX3, ...) and is downstream coupled to each one of the terminals via a downstream common link (Lc) and a tree-like distributive network. Each transceiver provides to a combiner (COMB) included in the head-end (HE) a downstream signal (Sd1, Sd2, Sd3, ...) in a frequency band (CH1, CH2, CH3, ...) associated to the transceivers (TRX1, TRX2, TRX3, ...). The downstream signals (Sd1, Sd2, Sd3, ...) are together combined into a downstream modulated signal (S-MOD) which is broadcasted from the head-end (HE) to the terminals. A first one (T12) of the terminals is upstream coupled to a first transceiver (TRX1) via an upstream link. The information is provided to the first terminal and concerns a filter frequency band (CH1) which is a first one of the frequency bands which has to be used by the first terminal to filter out of the downstream modulated signal a regenerated downstream signal associated to a first one (Sd1) of the downstream signals provided by the first transceiver (TRX1). The method inserts a pilot tone signal(P1i, P1j, P1k) in the downstream modulated signal within a predefined pilot tone frequency band (CHp1i). The pilot tone signal (P1i, P1j, P1k) includes the information concerning the first frequency band and the method filters out of the downstream modulated signal by the terminal with a derived frequency band (CHd1i, CHd1j, CHd1k) which is derived of the predefined pilot tone frequency band (CHp1i, CHp1j, CHp1k) the pilot tone signal (P1i, P1j, P1k).

Title: Programmably upgradable implantable medical device
Inventor: STOTTS LAWRENCE J
IPC: G06F21/12
Filed: 1997-05-14
Abstract: An implantable cardioverter/defibrillator device is implemented to be selectively non-invasively upgraded from time to time after implantation to enable the device to provide additional therapy for arrhythmia treatment as the patient's need for such treatment undergoes change. The device is adapted to provide a plurality of functions corresponding to different levels of therapy for treating arrhythmias, and to respond to each different type of arrhythmia that may be sensed, to supply a function which is designated as being appropriate to relieve that respective arrhythmia. Each function is not necessarily unique to treating a particular arrhythmia, and, in at least some instances, may be used to treat more than one of the plurality of different types of arrhythmias. At the time of its implant, the device is restricted from providing those of the plurality of functions which are deemed as being non-essential to the patient's needs at that time. From time to time thereafter, however, as the patient experiences periodic need for additional therapy, restricted functions of the device are selectively restored by external programming, but only if the programmer is able to supply to the device an enabling code which is substantially unique to that device. In this way, restoration of the restricted functions is locked out except with a prescribed key.

Abstract: In a steam cooling type gas turbine, a sealing structure for improving sealing performance between an interior of a rotor and a gas path of a turbine section which performs inter-disk sealing such that leakage of cooling steam and self-induced vibration of a baffle plate are prevented. A groove is formed along a circumferential direction in an end face of at least one of disk lands which protrude in opposition to each other between adjacent rotor disks, and an annular sealing member having an interior space is disposed in a sandwiched fashion, being brought into contact under pressure with an inner wall surface of the groove and an end face of the other disk land, or alternatively, an inner wall surface of a groove formed in the other disk land to thereby realize the inter-disk sealing structure for the gas turbine. Upon rotation of the turbine, sealing surface pressure is increased by centrifugal force to thereby reliably maintain sealing between the disks of the gas turbine, and the sealing performance in the gas turbine is improved.
